,HANS HOLZWAR-TH, or HAMILTON, 01110, ASSIGNOR'AOF ONE-HALF To I ERHARD JUNGHAUS, SR., OF SCHRAMBERG, GERMANY.

GAS-TURBINE.

Be it known that I, HANS HOLZWARTH, a

citizen of Germany, residing in Hamilton,

Butler county, Ohio, (post-oi'fice address Hamilton, Ohio,) have invented certain new and useful Improvements .in Gas-Turbines f of which-the following is a specification.

I O companying drawings in which':+

This invention, pertaining to gas turbines, will bereadily understood from the following acdescription taken in-connection with the Figure 1 is avertical lon itudinal section illustrating a construction gas-turbine embod'ying my invention: Fig.." 2 'a vertical transverse section in the plane of'line a of- Fig, -1, viewedfrom the left: Fig. 3 a vertical transverse section in the plane of line-b of N 'Fig, 1, viewed from the right, the outer section ofv the turbine-casing being removed,.

away: Fig., 4 a-vertical transverse section and a part of the turbine wheel being broken in the plane of'line c of 1, viewed from the left: Fig. 5 a vertical transverse section, on a smaller scale, in the plane of line (1 of Fig 1,,v-iew from the left: and Fig. 6 a horiz'ontal section, on an enlarged scale, in the plane of line e of Fig. 1, through one of the nozzles, the turbine appearing in plan.

In the drawings :'1., indicates a bed-plate:

2, a shaft bearingf'3, the turbine-shaft: 4

the turbine thereon: 5, the coupling-part on "the shaft, to adapt the general machine to connection with machines to be driven: 6, the turbine casing: 7 a circumferential series of explosion chambers formed at one wall of the f casingz 8, a circumferential series of nozzles, one for each OXPlOS-IOIL chamber, these nozzles leading from the explosion chambers to position to direct the gases to thevanes of the turbinet9, valves normally closing c'ommunica- -tion between the explosion chambers and the nozzles, these valves opening from the explosion chambers and toward the turbine, there being one for each explosion chamber; 10, a spring of adjustable tension connected with each of the valves and tending to hold it to its seat: 11, alarge hollow bearing in axial annular air-chamber in the boreof this bearingz 13, an air inlet connection to'this air chamber, the same being ad'aptedfor connec- 'tion'with any suitable sourcelof airsupgly under pressure: 14, an annular gas cham er formed within the bore of the bearing 11: 15,

' a gas inlet communicating with this gas chamber and adapted for communication with any suitable-source of su ply of gas under pressure: 16, exhaust 'outet from the turbine-casing: 17, a hollow revolver, considered asa whole, turning within thebeari 1-1: 18, a bearing formed Within the circle 0 the explosion chambers, its axis being coincident with that ofthe turbineand revolver: '19; the i hollow head of the revolver turning within the bearing 18: 20,.a diametrical partition-in the revolver,.dividing its generalinterior into two portions, one devoted to air and the other to gas: 21, a passageway leading from one of the general chambers of ,the revolver into constant communication with the air chamber 12 in the revolver bearing: 22, the

air chamber in the head of the revolver: 23,

a portion ofthe cavity of the general revolver forming a passage placing air passage 21 in constant communicatlon with air chamberchamber of the revolver in constant communication-with the gas chamber 14 of the bearing: 25, the gas chamber in the head of the revolver: 26, a portion of the general cavity of therevolver, placing gas passage 24 always in commumcation with gas chamber 25 in the head of the revolver: 27, a port leading from each explosion 'chamber'into the bearing 18, these ports bein normally closed 4 by the general periphery o the head of the revolver: 28, a port leading outwardly from the air chamber 22 in the head of the re-. 1

volver and adapted; as the revolver turns, to. communicate with the explosion chambers in successi on through their orts 27: 29, a similar port leading outwar y from gas chamber 25 and adapted, as the revolver turns, to

30,..a worm wheel fast on the revolver: '31, ,a worm engaging the worm wheel: 32, a motor connected with the worm to serve in giving too . 22: 24,- a'passage placing the second general Springs lOholding the valves at the explo sion chambers closed are to be adjusted to desired pressure of exit of gases from the explosion chambers.- Air is to be supplied con- .stantly to connection 13 at the proper pressure, this constantly maintalnmg-a pressureof air in airchamber 22 of the revolver head.

' Gas of proper pressure is to be supplied con-- stantly to connection 15, thus constantly maintaining a pressure of gas in the gas chamber 25 of the revolver head. Current is to be brought to the collecting rings to vitalize the lowingthis the igniter explodes the mixture in each explosionchaniber in succession. As

[a resultoi'the explosion the valves of the exyplosion chambers are. forced open and the products of the explosions pass through the nozzles and go to theturbine. The gas pressure should alvsfjays le some- What greater than the air pressure. Oil may 3 chambers m'the revolver, and the numb er'of lteutili zed' as a fluid in the machine. The number ofwheels {constitutlng the rotor of the turo1ne,;as well as the number of pairs of explosion chambers, may obviously; be Vadrawing is to be viewed as exemplifyi-ng'and ried,- and the character of the igniter is immaterial so long as it is adapted for its work.- The particular construction set forth' in the schematic.

I claim:

1; In a gas turbine, the combination, substantially as set forth, of a turbine-rotor, a casing therefor, an explosion chamberhaving an inlet and an outlet, a valve at said outlet opening away from, the explosionchamber; a spring ioldingsaid valve normally closed, a nozzle leading'from said outlet to the vanes of the turbine-rotor, a revolver having an airchamber and a gas-chamber provided each with an inlet connection and with an outlet port adapted to place them in successive communication with the inlet to the explo sion chamber, an igniter carried by the revolver across the inlet to the explosion chamb er, and meanskfor rotating the revolver.

. 2. In a gas turbine, the combination, substantially asset forth, of a turbine-rotor, a casing therefor, a series of explosion chambers each-having an inlet and an outlet, a valve'ateachoi said outlets opening away from the explosion chambers, a spring holding each valve normally closed, a nozzle leading from each outlet to the vanes of the turbine-rotor, a revolver having an air-chamber and-a gas-chamber provided each with an inlet connection and with an outlet port adapted to; place thenr in successive communication with the inlets to the explosion cham hers, an igniter carried by the revolver across the 1 inlets to; ithe explosion chambers, and

means for rotating the revolven;
